RHSA-2007:0220 - Security Advisory

Topic

Updated gcc packages that fix a security issue and various bugs are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The gcc packages include C, C++, Java, Fortran 77, Objective C, and Ada 95
GNU compilers and related support libraries.

Jürgen Weigert discovered a directory traversal flaw in fastjar. An
attacker could create a malicious JAR file which, if unpacked using
fastjar, could write to any files the victim had write access to.
(CVE-2006-3619)

These updated packages also fix several bugs, including:

• two debug information generator bugs
• two internal compiler errors

In addition to this, protoize.1 and unprotoize.1 manual pages have been
added to the package and __cxa_get_exception_ptr@@CXXABI_1.3.1 symbol has
been added into libstdc++.so.6.

For full details regarding all fixed bugs, refer to the package changelog
as well as the specified list of bug reports from bugzilla.

All users of gcc should upgrade to these updated packages, which contain
backported patches to resolve these issues.
